CHARLES NIOKLAS KALSTROM, OF MANSON, NORTH CAROLINA.

COMBINED SASH AND BLIND LOCK.

- KALSTROM, a citizen of the United States, re-

- former.

siding at Manson, in the county of Warren and State of North Carolina, have invented a new and useful Combined Sash and Blind Lock, of which the following` is a specifica-l tion.

The invention relates to improvements in combined sash and blind locks.

The vobject of the present invention is to improve the construction of combined sash and blind locks, and to provide a simple, inexpensive and efficient device of great strength. and durability, and adapted to be readily applied to a window, and capable of securely fastening both the shutters and the lower sash and of eiiectually preventing the same from being surreptitiously unfastened without making sufficient noise to alarm the occupants of a house.

lith these and other objects in view, the invention consists in the construction and novel combination ofparts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended. it being understood that various changes in the form, proportion, size and minor details pot construction, within the scope of the claims, may be resorted to without departing from the spirit or sacriiicing any of the advantages of the invention.

In the drawingz-Figure 1 is a vertical sectional view of the lower portion of a window, provided with a combined sash and blind lock constructed in accordance with this invention. Fig. 2 is a detail plan view partly in section, the shutters being partly open to illustrate more clearly the rigid catches or engaging members carried by the same. Fig. 3 is a detail perspective view of the spring actuated lever and the swinging catch, and the means for mounting the Fig. 4 is a detail-perspective view of the 'fixed catch of the sash. Fig. 5 is a detail perspective view of one of the rigid shutter catches.

Lilie numerals of reference designate corresponding parts in all the iigures of the drawing.

1 designates a spring actuated locking lever, having an enlarged head 2 for engaging a pair of rigid catches or members 3 of a pair of shutters or blinds 4. The locking lever, which is located beneath the sash 5,

extends from a point beyond the outer face Specification of Letters Patent.

of the -same to the inner face thereof, as clearly illustrated in Fig. 1 of the drawin and it is provided between its ends wit suitable pivots or trunnions 6, extending from the side edges of the locking lever and arranged in suitable bearing openings in ears 7. The ears 7 depend from a plate 8, which covers arecess 9 in the window sill 10. The plate 8 is arranged flush with the upper face of the window sill, and the lever, which is suspended by the ears from the lower face of the plate, operates the said recess 9. The

outer end of the plate extends to the outer stantially a horizontal position and they are formed integral with plates 12, which are secured by screws, or other suitable fastening devices to the inner faces of the shutters, as clearly illustrated in Figs. 1 and 2 of the drawing. The said engagin portions or catches are provided with eads, having beveled end faces and provided with shoulders 18 for engaging the shoulder 11 of the locking lever. When the shutters are closed, the catches 3, which are rigid with them, are automatically engaged by the locking lever, which is pushed upwardly by the beveled faces of the saidicatches 3, and as the catches 3 and the locking lever are concealed, the locking device cannot be operated. from 'the exterior. The plates 12,which are arranged at the meeting edges of the blinds, prevent an instrument from reaching the locking lever and form a metallic end wall for protecting the locking device, when the shutters are closed.

The locking lever is maintained in its en gaging position by means of a spring 14, secured at one end to the lower face of the lever below the center thereof and extending inwardly or rearwardly therefrom. The spring 14 is arranged at an angle to the inner arm of the locking lever, and the free end bears against the window sill at the bottom of the recess 9.

The inner arm of the locking lever is slotted or bifurcated, and the sides of the slots or bifurcations are partially coiled or rolled to form spaced eyes 15 between which is arranged an eye 16 of a hinged catch 17. The catch 17 is connected with the innerarm oi the locking lever by means of a pivot or pintle 18, which is arranged in the eyes 15 and 16. The catch 17, which is adapted to swing toward and from the sash 5, operates in an extension 19 of the recess 9, and it is provided at its upper end'with `an engaging portion or head 20, and it has a linger piece 21. The head 20 extends inwardl piece extends upwardly, or in the opposite direction from the head.. The head 20 of the catch 17 engages alixed catch 22 of the sash 5, `wherebythe latter is locked in its closed position. The fixed catch 22 consists of a lip or ilange, formed integral with a lift 23, which is secured to the sash 5 at the bottom thereof, as clearly shown in Fig. 1l of the drawing. `The lip or flange of the lift 23 forms an upper recess or seat, with which the engaging portion 20 ci the swinging catch 17 is interlocked. The swinging catch besides forming a lock for the lower sash, constitutes operating means for actuating the locking lever to reach the shutters. By depressing the swinging catch 17, the outer` arm of the locking lzever is lifted out of engagement with the catches of the shutters.

The shutters, when closed, are automatically locked by the lever, which may be readily swung into and out ci engagement with the: When the shutters and4 catch of the sash. the sash are locked, they cannot be unfastened from the outside of the window, and itl will be necessary to cut the slats of the shutters and break the glass of the window in order to reach the swinging catch from the outside. When the swinging catch is in en gagement with the sa'sh, it rigidly maintains the locking lever in engagement with the` shutters, and prevents the outer end of the arm of the lever from swinging upward out of engagement with the rigid catches of the shutters.

Having thus fully described my invention, what l claim as new and desire to secure by Letters Patent, is

1. ln a device of the class described, the combination with a pair ci' shutters provided with catches, and a sash, of a pivotally mounted lever extending beneath the sash and provided at its outer end with means for engaging the shutter catches, said lever lbeing arranged to swing on its pivot to engage, and release the said catches, and a movable catch connected with the inner end of the lever and arranged to move toward and from the sash or inl Athe direction of the sash 5, andthe linger and provided with means for engaging the latter to lock the same and for holding the lever in engagement with the shutter catches.

2. In a device ol the class described, the
